Wired Mask: FF:FF:FF:FF:FF:FF
•
Wireless MAC Address: 00:02:2D:51:94:E4
•
Wireless Mask: FF:FF:FF:FF:FF:FF
•
Result: Traffic between the Wired Server and Wireless Client 1 is blocked. Wireless Clients 2
and 3 can still communicate with the Wired Server.
Prevent Multiple Wireless Devices From Communicating With a Single Wired Device
Configure the following settings to prevent Wireless Clients 1 and 2 from communicating with
the Wired Server.
Wired MAC Address: 00:40:F4:1C:DB:6A
•
Wired Mask: FF:FF:FF:FF:FF:FF
•
Wireless MAC Address: 00:02:2D:51:94:E4
•
Wireless Mask: FF:FF:FF:00:00:00
•
Result: When a logical "AND" is performed on the Wireless MAC Address and Wireless Mask,
the result corresponds to any MAC address beginning with the 00:20:2D prefix. Since Wireless
Client 1 and Wireless Client 2 share the same prefix (00:02:2D), traffic between the Wired
Server and Wireless Clients 1 and 2 is blocked. Wireless Client 3 can still communicate with the
Wired Server since it has a different prefix (00:20:A6).
Prevent All Wireless Devices From Communicating With a Single Wired Device
Configure the following settings to prevent all three Wireless Clients from communicating with
Wired Server 1.
Wired MAC Address: 00:40:F4:1C:DB:6A
•
Wired Mask: FF:FF:FF:FF:FF:FF
•
Wireless MAC Address: 00:00:00:00:00:00
•
Wireless Mask: 00:00:00:00:00:00
•
Result: The Access Point blocks all traffic between Wired Server 1 and all wireless clients.
Prevent A Wireless Device From Communicating With the Wired Network
Configure the following settings to prevent Wireless Client 3 from communicating with any
device on the Ethernet.
Wired MAC Address: 00:00:00:00:00:00
•
Wired Mask: 00:00:00:00:00:00
•
Wireless MAC Address: 00:20:A6:12:4E:38
•
Wireless Mask: FF:FF:FF:FF:FF:FF
•
Result: The Access Point blocks all traffic between Wireless Client 3 and the Ethernet network.
